It is generally assumed that hydrocarbons such as petrochemicals are formed under extreme heat and pressure, conditions that mankind assumes can only take place under the surface of the earth where biological elements might be sandwiched between layers of the Earth's surface. They also form in the air during every passage of the 12th Planet, as all the components are in the atmosphere - carbon, oxygen, and hydrogen. During a pole shift, violent volcanic explosions take place, super-heating the air passing overhead. Combined with continuous lightning flashes in some places, many chemicals form readily which under ordinary circumstances do not form in the atmosphere. Some of these chemicals are what humans term petrochemicals, but their close cousins, carbohydrates, form also.
It is written in many parts of the world that after a pole shift, what the Jews called manna was found lying on the ground in the morning dew. Beads of carbohydrates that tasted like honey, and where landing on water turned the water milky, so that those lands where this occurred were sometimes known as the lands of milk and honey.
Not all locations find this handy food delivered for breakfast, and not all such food can be gathered and eaten by the eager humans, as there is competition from the bugs and rodents in the area who seem to need less sleep than the weary and malnourished humans scrambling about in the gloom upon rising. Manna is formed and dropped in those parts of the world where the air has just passed over active volcanoes. It is formed to some degree during normal times, but becomes pronounced after a pole shift due to the exponential increase in volcanic activity. Other parts of the world find no such gift beading the ground in the dawn, and residents of those parts that are fortunate in this regard must rise early and scramble if they are to collect any manna at all. Not only is it eaten by anything that can crawl, it also melts and seeps into the ground during the heat of the day.
